Patent CA-2329889-A1 (CA)
Inventor: ABDULKADER BARBIR
IPC: H04K1/02
Filed: 2000-12-29
Abstract: The invention allows the introduction in real-time of at least sufficient security to minimize the risk of intruders overhearing data on a particular link. This reduces the risk of being victim to either a Type 1 - Unauthorized access threat or a Type Message sequencing threat. The method involves encryption at the physical data link level where the form of the encryption affects groups of data bits. The effect of introducing the invention is to add noise to the signal in such a way that it can be subtracted from the received signal leaving only the original signal. The resulting signal, were it to be observed by a person other than the intended recipient, would have an effective Signal to Noise (S/N) ratio of less than 1. The masking effect of this added 'noise' signal hides the original signal from any eavesdroppers, since it well-known in the art that for a non-periodic signal to be effectively recovered it must have a S/N greater than 1.

Title: Method for detecting stress and strain
Inventor: LAM DUHANE
IPC: G01B11/16
Filed: 2001-05-22
Abstract: A method of detecting stress and strain using a powder coat finish and photoelastic techniques. A part is provided with a photoelastic layer comprising a non-opaque powder coat finish that becomes optically anisotropic when stressed. Photoelastic techniques are used to detect and measure stress and strain in the part. Fringe patterns appear in the photoelastic layer indicating the locations and magnitudes of the stress and strain when the part is illuminated with polarized light and viewed through a polarizing filter. Stress and strain resulting from applied forces are detected. Structural deformation in parts that have experienced plastic deformation is also detected. Photoelastic techniques using powder coat as a photoelastic technique are less expensive and easier to apply than traditional photoelastic coatings. Applications include testing of prototypes, stress testing, inspection and monitoring of production parts, and anywhere that viewing and measuring of stress and strain are of interest.

Title: System for detecting and communicating operational characteristics of tires telecommunicationally and a method therefor
Inventor: LAITSAARI JUHA
IPC: B60C23/04
Filed: 2001-06-26
Abstract: A system for a tire to be mounted to a vehicle allows each of the wires to communicate with a mobile communicator, such as for example a mobile phone. The system includes typically at least sensors for monitoring and measuring the pressure and temperature of the tire. The measured parameters of the tire are fed to a processor that compensates the measured pressure with the measured temperature.    The temperature corrected tire pressure is then stored in a memory store. A communications module, operating under a wireless data link protocol such as for example the Bluetooth protocol, sends the stored information to a mobile phone, in response to a request thereby. The temperature corrected data of the tire is also transmitted to the other tires of the vehicle. Any one of the systems relating to the tires may act as the server of all of the other tires for transmitting the information of the respective tires of the vehicle to the mobile phone, which acts as the browser. Alternatively, the mobile phone could request that information of the various tires be sent to it individually by the systems of the respective tires.

Abstract: Method for providing precured innerliners (50) having a predetermined cross sectional profile for use as part of a pneumatic tire assembly used in a bladder-less shaping and vulcanizing mold. The innerliner (50) is formed from a continuous strip of elastomeric material (12) hot formed using a calender assembly (10) with a profiled calender roller (16). The formed strip is cured "in-line" in a press (38) having a profile matching platen (80) before being wound onto a tire building drum (48). After the pneumatic tire assembly is completed, the assembly is shaped and cured in a bladder-less mold, utilizing the precured innerliner as the impervious inner layer. Initially, the center region (62) of the innerliner is at least twice as thick as the lateral regions (72, 74). In the finished pneumatic tire, the innerliner exhibits a uniform thickness.
